MILWAUKEE -- The Brewers finalized their 2011 Minor League coaching staffs on Wednesday with a pair of promotions.Jeff Isom, who managed the past two seasons at Class A Wisconsin, was bumped one level to "advanced" Class A Brevard County in the Florida State League for 2011. He's replaced at Wisconsin by Matt Erickson, who spent the past two seasons on Isom's staff as hitting coach. Erickson grew up in Appleton, Wis., where the Timber Rattlers play their home games, and enjoyed a brief, four-game stint with the Brewers in 2004. "I am very excited to get the opportunity to manage a Brewers affiliate in my hometown," Erickson in a statement from the Rattlers. "The Brewers are the organization that I grew up watching. They gave me a call up to play in the big leagues and now a chance to help develop the young talent in their organization." Erickson had been the Rattlers' hitting coach for the past two years. The team also announced that pitching coach Chris Hook and athletic trainer Jeff Paxson both would return for 2011, and that former University of North Florida head coach Dusty Rhodes would replace Erickson as hitting coach. Rhodes has a long baseball resume, including stints as a manager and coach in the Brewers' Minor League chain from 1988-91. He founded the University of North Florida baseball program and spent the last 23 seasons as head coach, making 16 postseason appearances, including five trips to the College World Series (two in NAIA and three in NCAA Division II). Tim Gifford has been assigned to the Timber Rattlers as the strength and conditioning coach. In Brevard County, pitching coach Fred Dabney (seventh season), coach Dwayne Hosey (second season) and athletic trainer Tommy Craig (fifth season) will all return to work under newcomer Isom, who will manage his fourth different Brewers affiliate in five seasons. Isom takes over for former Manatees manager Bob Miscik, who moves to roving infield instructor. That role was previously held by Garth Iorg, who was named Brewers first-base coach in October. The Brewers announced that the rookie-level Helena Brewers staff would return intact after winning the Pioneer League Championship in 2010. Manager Joe Ayrault will be back for a second season and pitching coach Elvin Nina, coach Ned Yost IV and athletic trainer Jimmy Gentry will each return for their third season with the team. The Dominican Summer League Brewers will enter their second season as a Brewers farm team in 2011 and will again be managed by Nestor Corredor, who played in the Brewers organization from 2004-08. Pitching coach Jose Nunez and coaches Jose Pena and Luis De Los Santos will also return. Eduardo Brizuela will serve his second season as coordinator of administration -- Latin American operations. Back home in Milwaukee, the Brewers promoted Mark Mueller to manager, administration -- player development. Earlier in the offseason, the Brewers announced that the coaching staffs at Triple-A Nashville, Double-A Huntsville and rookie Arizona would remain intact from last year.
